ADVANCED CHEMISTRY FOR MUNICIPAL & INDUSTRY

As blue green algal blooms become more frequent, management of them has become more critical.
Treatments have become more complex and expensive – think mechanical aeration and ultrasonic sterilisation.
Earth Science Laboratories took a different approach.
What if traditional and simple algaecides could be made dramatically more effective?

EARTHTEC ALGAECIDE

  • Almost 100% bioactive copper in the novel formulation
  • 50-80% less copper than other copper sulphate-based products

  • Visible results in 24-72 hours
  • Eliminates harmful BGA in as little as 96 hours
  • Halts cyanobacterial growth

  • Halts production of cyanotoxins

  • Up to 30-day control with one application
  • Reduces taste and odour compounds, such as geosmin

  • Eliminates expensive mechanical treatment

  • Eliminates expensive electrical treatment

  • Reduces labour costs

  • Algal cells biodegrade, becoming food for living organisms

58% less copper dosage to treat freshwater green algae

Recent research shows how much less copper dose is required to effectively treat algae using EarthTec versus copper sulfate.

This graph shows the percentage inhibition rates of algae growth after 96 hours of exposure to copper delivered as conventional copper sulphate compared to EarthTec.

Recent research shows how much less copper dose is required to effectively treat algae using EarthTec versus copper sulfate. This graph shows the percentage inhibition rates of algae growth after 96 hours of exposure to copper delivered as conventional copper sulphate compared to EarthTec.

Using a conventional copper treatment (CuSo4.5h20), nearly two and half times the copper dosage was needed to achieve the same algae inhibition.

The tests were performed by Aquatic BioAssay and Consulting Inc., against the indicator algal species, selenastrum capricornutum, according to standard bioassays of chronic exposure, 96 hours.

ALGAE CONTROL

Problem
Global warming has increased frequency of algal blooms. Increased use of copper sulphate isn’t the answer. If traditional copper sulphate is used, copper can build up over time, impacting marine life, and algae can develop a tolerance.

Solution
A fundamental rethink of how to make algaecides more effective and less harmful.

CASE STUDY

In addition to controlling problematic algae and BGA in this application, EarthTec reduced geosmin concentration from 11.5 ppt to 1.85 ppt in 4 days
